The specific embodiment
Specify the specific embodiment below in conjunction with Figure of description.
As Fig. 1, Fig. 2 and shown in Figure 3, the described milling train of present embodiment is a cold-rolling mill, and rolled piece is realized plastic deformation by roll under normal temperature or 300 ℃.Milling train divides three kinds of working methods: backing roll transmission Φ 60/ Φ 300 * 300mm, Φ 90/ Φ 300 * 300mm, working roll transmission Φ 150/ Φ 300 * 300mm.Draught pressure reaches 120 tons, and mill speed is less than 30m/min.Adopt an alternating current generator to drive backing roll or working roll respectively.Adopt two alternating current generators to adjust roller gap.
Present embodiment comprises motor 1, shaft coupling 2, decelerator 3, two headers 4, universal-joint spindle 6 and working stand 7, and described working stand 7 comprises electric screw down gear 71, two working roll parts 72, two backing roll parts 73 and frames 74; As shown in Figure 4 and Figure 5, described working stand 7 also comprises working roll cushion block 75 and pressing plate 76, working roll cushion block 75 is arranged between the front and rear end of the madial wall of described frame 74 and working roll bearing block 77, and described working roll cushion block 75 is fixed on the madial wall of described frame 74, and an end of described pressing plate 76 is fixed on the frame 74 and its other end restraint of labour roll bearing seat 77 moves axially.Wherein, totally two groups of screwdown gears are installed in respectively above the frame, through left and right each one depress motor and two-stage worm gear, worm gear pair passes to housing screw after slowing down, housing screw is fixed on by screw box in the middle of the window of every frame, by breading cap and bascule roll is moved up and down.Depress brake is installed on the Motor Shaft, make housing screw obtain positional precision accurately.Screwdown gear is to be quick on the draw, to keep the depth of parallelism of correct roll gap aperture, given drafts, adjustment double-working.
Preferably, described working stand 7 also comprises working roll liner plate 78, and working roll liner plate 78 is arranged between the front and rear end of working roll cushion block 75 and working roll bearing block 77, and described working roll liner plate 78 is fixed on the working roll cushion block 75.
More preferably, as shown in Figure 6 and Figure 7, present embodiment also comprises branch axle box 5, be disposed with four pitch wheel axles in the described minute axle box 5 from top to bottom, and the power intake that is followed successively by gear shaft 51, No. two gear shafts 52, No. three gear shafts 53 and 54, numbers gear shafts 51 of No. four gear shafts and No. four gear shafts 54 is from top to bottom fixedlyed connected with two clutch ends of two headers 4 respectively; The clutch end of a gear shaft 51 and No. four gear shafts 54 is connected with the power intake of two backing roll parts 73 respectively or the clutch end of No. two gear shafts 52, No. three gear shafts 53 is connected with the power intake of two working roll parts 72 respectively.
